World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. At two sites along the lake, the researchers uncovered clay-filled fractures, signs of soil liquefaction and polished rock shear fractures called slickenlines, that point to at least three past earthquakes in the area. Events of magnitude 5–6 are estimated to occur once every 200 to 300 years. In historic times, the ETSZ has not produced earthquakes larger than magnitude 4.8. Eastern Tennessee Seismic Zone (ETSZ) The Eastern Tennessee Seismic Zone (ETSZ) is one of the most active areas in the southeastern U.S. Its known faults are generally ancient and no known active faults reach the surface. In the East Tennessee Seismic Zone, there have been 188 earthquakes of magnitude 2.5 or greater since measurements began in the 1970s. 5G and future 6G terahertz absorbed by water vapour = heating? WHEBN0017181125 Due to proximity to the New Madrid fault line, most structures in Memphis are retrofitted to withstand earthquakes, but homes and buildings in Middle Tennessee generally do not have such prerequisites and likely will not need them.

We mapped concentrations of sackungen (ridgetop spreading features) on bluffs along the eastern Mississippi River valley in northwestern Tennessee that likely form or are reactivated during large earthquakes. The level of the lake is drawn down in winter to accommodate snowmelt, which exposes river sediments and the signs of past seismic activity.

The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. "But we don't have enough data right now to say whether or not this is some kind of ephemeral or maybe periodic activity," he noted.

John Bellini, a geophysicist with USGS, said “there is a history of earthquakes” in the Eastern Tennessee Seismic Zone, which extends into northwest Georgia and northeast Alabama. Using a technique called optically stimulated luminescence to assign dates to the minerals contained in sediments surrounding these seismic features, Cox and colleagues narrowed the possible ages of these earthquakes to between 25,000 and 15,000 years ago.
